(54) DEVICE FOR ORDERING, SORTING

AND TRANSFER OF PARALLELEPIPEIDAL ENCLOSURE

CARGO, IN PARTICULAR FORM BREAD

one

The invention relates to a device for arranging, sorting and transferring a paralleleepiped piece weight, in particular pan bread, which for the purpose of further automatic processing in the processing plant is transported or supplied with specified dimensions, with certain tolerances and in a certain position.

Known shipping devices in which a piece of cargo repeatedly passes several lines. In this case, the weights must have a certain position according to the shape and dimensions before it enters the guides, because otherwise the wiring is not secured and congestion occurs in the transport device.

In the known devices according to DE OS 22 06 211, there are no special arrangements for ordering and sorting. In order to ensure the optimal position of the piece cargo, it is necessary to control and adjust its supply by additional service personnel.

Also known are devices in which a change in the position of a piece load is carried out by transferring the load at a right angle from time to time by a working device driven by a pneumatic cylinder, or similar devices.

However, in these devices, the supplied (in the wrong initial position) piece weight enters subsequent transport devices and processing machines, which leads to a disruption of the technological process.

The known device, equipped with a circulating scraper chain and complex electrical control, such as a light sensor barrier. Transportation also occurs intermittently here, namely when the piece-load has already occupied a predetermined position.

However, these devices require relatively high costs for control systems, and intermittent operation limits their performance. The high wear and tear, and therefore the short service life of parts, is due to the high switching frequency of clutches and electric motors. In addition, malfunctions in the device may occur if two piece loads, located side by side and closing each other, pass by the light barrier. Cargo arriving in the wrong position, although transmitted at right angles, is transported further in the wrong position.

Known devices, which are called overturning draining trays.

They are made mostly of sheet metal.

steel in the form of shafts, in which the piece weight slides down in the descent section under the force of gravity, and can be turned over on the spherical turning surface. For example, from vertical to horizontal position. The disadvantage of these devices is that the mixing, the carrying force can vary greatly depending on the (change in attitude) of the friction, and also due to the change in the dimensions of the load, and the weight of the weight can be insufficient for (reliable) transportation through the overturning drain chute. The load arriving in such a tray in the wrong starting position leaves it also in the wrong position.

Devices according to DE-OS 22 49 043 and DE-AS 24 27 281 are also known, which serve for the installation of bottles (glass equipment) and the like. from horizontal to vertical position, with the bottles on the conveyor with transverse straps placed at a certain distance from each other being installed from a horizontal position to a vertical position with the help of an installation device with inclined working surfaces on which the bottles run.

However, these devices are primarily designed for rotationally symmetric loads. Only installation and orientation of these weights are possible, but they do not perform sorting in the presence of deviations from shapes and dimensions. Further, they have the disadvantage that objects placed in a vertical position can not enter the device in any position, they can only be in two different positions, otherwise the reliable operation of the device is not guaranteed. All the above mentioned devices have the general disadvantage that the piece weight cannot be transferred from the wrong initial position to the final correct position, it is transferred in the wrong position to subsequent devices for transport and processing, and if there are deviations from the form, the sorting cannot be performed piece cargo. Therefore, the automatic mode of these devices is not possible, and additional personnel are needed to control and arrange piece cargo.

The purpose of the invention is the creation of a continuously operating device, which captures with the help of suitable devices the force load on the conveyor and in the irregular position on the conveyor and during the movement of the conveyor carefully arranges the piece load, sorts or puts the load in the correct position with deviations from the shape or shape. with the wrong position, and transfers the load only in a certain position to the subsequent device for transportation and processing, which eliminates the need for visual observation and manual redvaritelnoy sorting to avoid accidents and congestion, and thus completely automates the process.

The invention is based on the task of creating a continuously operating device. to capture, guide, order, sort, or install in the correct position and to transfer in a definite position to a subsequent device for transporting and processing incoming randomly parallelepiped piece goods, which are automatically activated by forced control in conjunction with further wiring piece goods along a predetermined trajectory and with successive guiding devices, so that the subsequent device for transporting and processing before It is only a piece goods, which at each interval portion sequencer and sorting emphasis has required position and does not have deviations exceeding predetermined tolerance, and simultaneously the maximum possible flow of piece goods is avoided traffic jams and accidents, and is provided retraction of the sorted piece goods.

The goal is achieved by the fact that the profile frame, which is ush with a supporting structure for a rotating driving device and an adjustable drive, is located relative to the driven roller table in such a way that the center of the ordering and sorting section at an angle to the roller table is exactly below the line of transporting the leads, and the leads can turn in one direction in the direction of movement of the roller table, and the angle of rotation is limited by guide tires.

The roller conveyor is equipped with side guiding devices which, in front of the rotating drivers, pass into a rotatable spring-loaded (deflecting) flap. At the site of ordering and sorting, a known sorting (spherical) surface is followed by a sorting (adjustable) device. The sorting device consists of a slide, which is adjustable with an inclination towards the surface, for guiding the forcibly pushed piece cargo, as well as from the upper and following lower guide rods. The task of the upper and lower guide rods is that the piece load arriving in the correct position is passed, and the piece load coming in the wrong position due to the wrong center of gravity or deviations from the dimensions slips under the top guide rod or tilts through the bottom guide rod. Adjacent to the sorting area is a discharge tray for sorted piece goods. In the transport direction there is a transfer shaft for transferring piece cargo to a subsequent transport and processing device. Piece weight is delivered by the roller conveyor to continuously rotating leads and is gripped by it when the leads move from top to front. The input position of the piece goods at this location determines whether the piece goods will be transferred in the required position to a subsequent device for transportation and processing or it will be sorted. When forcedly driving an axial load through an ordering and sorting section consisting of a turning (spherical) surface, adjustable sliding surface, upper and lower. (Guides) X2 rods, the piece weight is felt, ordered and sorted depending on the shape and dimensions. and the center of gravity. The sorted piece weight is removed from the transport system through a discharge chute located under the sorting section. The piece weight, the passing section of ordering and sorting in the correct position, through the transfer shaft enters the subsequent device for transportation and processing. If the axial load is fed from the roller table between the two rotating leashes, then the piece weight is immediately captured. If, at the moment of supplying the (forced) area of the rotating leads, the axial load collides with one of them, then the latter deflects in the direction of movement of the roller table by the force pushing the unit load, passes in the deflected position past the axial load and then returns to normal (vertical) position under its own force of gravity. Piece load, which is located in front of the stop at the end of the roller table, is captured by the next driver and advances through the ordering and sorting section. If the loading weight at the moment of arrival lies on the roller table along the direction of the bilge, then it either rotates the rotating leads 90 ° to the direction of movement and is directed to the ordering and sorting section, or is pressed to the spring-loaded rotating flap and slides off through the discharge tray. FIG. 1 shows the entry of pan bread into a device for ordering and sorting; in fig. 2 - passing the bread pan through the device for ordering and sorting; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; in fig. 5 shows a section B-B in FIG. 2; in fig. 6 - section G-Y in FIG. 2; in fig. 7 is a section d-d in fig. 2. The main frame of the ordering and sorting device forms a light-profile frame 2 in which two reversible roller chains rotate 3. On the opposite overlays of the roller chains 3, jumpers 4 are mounted, in the middle of which the rotary leashes 5 for pan bread 9 are strengthened. arriving at the roller conveyor 1, is fed into the area of the roller chain 9 lead. If the tin bread 9 encounters a passing lead 5, the latter deviates in the direction of movement of the roller table 1 by the force moving the bread bread 9, um 9 by tin bread in a deflected position (position I) and then returns under the action of gravity to the normal position (position II). The angle of deflection of the leads 5 is limited on one side by the guide tires 10. The next lead 5 moves the tin bread 9 from the roller table I down to the ordering and sorting section. If the tin bread 9 enters the (gap) between the two leads 5, it is immediately captured and shifted to the ordering and sorting section. The stop 6 provides for the capture of bread in a certain place of the roller table 1. On the last bread the bread is guided by the side guides 7. The spring-loaded (deflecting) breadboard 8 is deflected in case of congestion caused by the incorrect position of the mold bread 9 served by the roll table 1 and the molded bread slides through the discharge chute 16. Separate tin breads 9 in any position are shifted from the roller table 1 to the area of turning and a are set by the turning spherical surface 11 in such a way that they fall are given at a certain angle to the plane on the sliding surface 12 installed at the same angle. The sliding surface 12 is limited in region b by an upper guide rod 13, and in area c a lower guide rod 14. The guide rods 13 and 14 are designed to ensure that the correctly rented pan bread 9 is passed through, and the incorrectly lying pan bread 9 due to incorrect the position of the center of gravity or deviations from the dimensions slipped under the upper guide rod 13 or tilted through the lower guide rod 14.

Molded bread 9, which has cut through the sorting areas b and c, slides into the transfer shaft 15, is set by transferring the inclined sliding surface 12 to a flat surface and is transmitted in (this position) to a subsequent device for transport and processing.

The whole process of turning, ordering and sorting takes place with the continuous movement of the leads 5, i.e. The proposed device can always receive, arrange, sort and pass on the tin bread.
